Question

When resistances are connected in series, the effective
resistance increases. Why?​

Answer 1

Answer:

(a) Connecting a number of resistors in series is equivalent to increasing the effective length (l) of the conductor. Recall R∝l. (b) Connecting a number of resistors in parallel is equivalent to increasing the effective cross-sectional area (A) of the conductor Recall R∝1/A

Answer 2
